12 = r - (34 - 2)
subtract he 2 from 34
12 = r - (32)
add 32 to each side
r = 44
Check:
12 = 44 - (34 - 2)
12 = 44 - 32
12 = 12 :)

Answer:
X= 2/5 y=-2
Step-by-step explanation:
5x + 2y = -2
3x - 5y = 11.2
Using the elimination method
Multiply equation 1 by 3
Multiply equation 2 by 5
15x + 6y = -6
15x - 25y = 56
Subtrat 3 from 4
-31y= 62
Divide both sides by -31
y= -2
To arrive at x, substitute y= -2 in equation 1
5x + 2y = -2
5x + 2(-2)= -2
5x -4 = -2
Collect like terms
5x= -2+4
5x= 2
Divide both sides by 5
x= 2/5
$3.15 because 5,25 divided by 5 is 1.05 times 3
Answer:
8
Step-by-step explanation:
from the graph, we can see that when x = 1,
f(1) = 10 and g(1)= 2
hence
f(1) - g(1) = 10 - 2 = 8
